Hello, I got excited when I understood the Collatz conjecture. I have some ideas that I want to try out but I am stuck on where to begin. I allready know some fundamentals, but want to learn more math to analyse the numbers related to the Collatz function. But, that in regards to base2 numbers. I have background in programming, binary numbers and a little on Cellular Automata allready. I took elementary college course on derivation and integration, but have found no use of it yet. Im looking for ideas, talks and discussions and the like about the Collatz conjecture and its issues. Also willing to learn more math on this issue. I saw allready someone had started a thread about this, but ill just repeat how the Collatz function is defined: C(x) = if x=odd then { 3x+1 } else if x=even then { x/2 } And so the collatz conjecture states that any initial number x will eventually reach 1 (or cycle: 1,4,2,1,4,2,...). I found out that if C(x) reaches a pow2 number (that is any 2^n number: 1,2,4,8,16,32,64,..etc) then it will automatically reach 1. And after googling it, I saw that that was allready known information of course. So looking at the bits of how these C(x) numbers behave, its almost like a Galois pseudorandom number generator (which is mostly about polynomials). And something that people have figured out (correct me if I am wrong) is that the odd part of the condition is changed to {(3x+1)/2} also shortcuts the branches to reach the number 1, but if it is proven someway it will also prove the original conjecture. Anyways, is it possible to prove something by entropy of binary numbers like taking the hamming weight (or some other trick) of the bitstring that the C(x) function creates? And the patterns that often occurs in one of the numbers is the ...100000001 pattern and the stuff inbetween just permutates into something like (pow2)....10000... and shifts to the right. Wikipedia have a nice paragraph about how to do this with bitmanipulation. Anyways, ill stop rambling and ask if people have some thoughts and ideas on the patterns made by the Collatz function and analysismethods (preferably in base2) like discreet methods. Thanks for your time. (Also i posted a similar idea in mathexchange forum but just got flamed all the way.. Im not out after wannabemathematicians to downvote a thread and say that I have not solved the Collatzproblem, because I have never claimed that I have. Im just out after collaboration and im willing to learn more math, I want creative responses rather than: what do you mean by this and that)..
